SnailSVN

SnailSVN is a TortoiseSVN-like Apache Subversion (SVN) client, implemented as a Finder extension. It allows you to access the most frequently used SVN features directly from the Finder context menu. SnailSVN also adds icon overlays to your SVN working copies in Finder. It tracks your SVN working copies and updates the icon overlays automatically, giving you visual feedback of the current state of your working copies.
